Rational expressions are multiplied and divided the same way numeric fractions are.

Point Q is located at (-4, 6). Point R is located at (8, 6).

Bess [88]

Step-by-step explanation:

Hi there!

Given;

Point Q is located at (-4, 6). Point R is located at (8, 6).

Note: Use distance formula.

Now;

$(d) = \sqrt{( {x2 - x1)}^{2} + ( {y2 - y1)}^{2} }$

Keep all values;

$(d) = \sqrt{ {(8 + 4)}^{2} + ( {6 - 6)}^{2} }$

Simplify;

$(d) = \sqrt{( {12)}^{2} }$

Therefore, the distance is 12 units.

Hope it helps!

Please help me! Please! I am so lost! Pythagorean Theorem!

Ket [755]

Answer:

Part A- yes, because all 3 sides are Equal (each side is 5)

Part B- yes, each rectangle has the dimensions 12*5

Part C- yes- since the sides are 5 and 12 you can determine that the diagonal is 13, using they Pythagorean theorem $a^{2} +b^{2} =c^{2}$

$5^{2} +12^{2} =13^{2} \\25+144=169$ - true statement, so the lateral sides are rectangles, because the corners are 90

Part D- $4\sqrt{2}$ (it is a 45-45-90 triangle- so the hypotenuse is the side length times $\sqrt{2}$

Part E- the diagonal face as the largest area- dimensions are $4\sqrt{2} * 12\\$

the area would be $48\sqrt{2}$

a sequence has a first term of 2 and a constant ratio of _3/2 what are the first five terms of the sequence

soldi70 [24.7K]

This is a geometric sequence with a=2, r= -3/2.
Therefore,
a₁ = 2
a₂ = 2*(-3/2) = -3
a₃ = 2*(-3/2)² = 9/2 = 4.5
a₄ = 2(-3/2)³ = -27/4 = -6.75
a₅ = 2(-3/2)⁴ = 81/8 = 10.125

Answer:
In fractions, the first five terms are
2, -3, 9/2, -27/4, 81/8
In decimals, the first five terms are
2.000, -3.000, 4.500, -6.750, 10.125
